OBJECTIVES OF VRx PROJECT<br />
VRx project was conceived in order to solve the problems which derive from the installation of a high quality<br />
car audio system. The long and constant work made with professional installers and the use of the most<br />
advanced, currently available technology allowed audison’s designers to attain totally new results in terms of<br />
power, reliability and exceptional versatility above all. “VRx SYSTEM” derived from this: it is a complete line of<br />
integrated electronic circuits made by amplifiers, active crossovers and signal processors, characterised by a<br />
common conceptual system called Open Deck Construction.<br />
Open Deck Construction<br />
It’s the heart of VRx SYSTEM. It indicates the “totally open construction” of VRx SYSTEM. A sophisticated pre<br />
section can accept several modules (MODULAR EXTENSIONS) which are put before the amplifiers and allow<br />
their functioning configuration. The integration between amplifier and signal processors permits to reduce<br />
signal paths as much as possible and to obtain performances which are not commonly attained through<br />
separate units.<br />
Modular Extensions<br />
They are divided into:<br />
• CONTROL EXTENSIONS: signal processing and control modules and cooling modules. They can be used<br />
into all VRx.<br />
• MULTICHANNEL EXTENSIONS: crossover modules which can be employed in one and two channel<br />
amplifiers (VRx1 and VRx2). Multichannel VRx (VRx4 and VRx6) are already supplied with a sophisticated, reconfigurable<br />
crossover.<br />
• COOLING DUCT EXTENSIONS: terminals and raccords which allow air ducting inside and outside the heat<br />
sink, directing its flux in order to improve cooling. If cooling modules are not used, Cooling Duct Extensions<br />
can be employed for esthetical purposes.<br />
ABS ® - AUDISON BALANCED SYSTEM<br />
All VRx amplifiers have balanced inputs and, if supplied with integrated crossover or Multichannel Extensions,<br />
they also have balanced outputs. They use audison cable ABS connectors, which allow balanced connection<br />
through an exclusive panel connector which is as big as standard RCA ones. They can accept signals up to 5V,<br />
in order to be as compatible as possible with all sources which can be found into the market.<br />
VRx AMPLIFIER<br />
While developing VRx project, utmost attention was paid to the following aspects:<br />
• dynamics, which involves power supply and amplifying stage<br />
• reliability and, thus, protection and cooling<br />
• sound quality.<br />

VRx amplifiers have high power, which can guarantee very good dynamics even in car. In order to be able to do<br />
this, power supply is oversized and has the same structure as HV series one.<br />
Power supply is protected from overloads and excessive voltages (due to the car voltage controller breakdown or<br />
to the battery charger fault, for instance). Protection against short circuits or against too low loads onto speakers<br />
outputs were also introduced, as well as in case there is direct current on power signal.<br />
Thermal protection is double: it traditionally controls heat sink temperature but also power supply transformers one.<br />
